The objects of this invention are to provide a roller for travelingconveyers which will materially reduce the labour and exv pense ofreplacement of broken or seized rollers and will reduce to the minimumthe tlme consumed in re-mounting rollers requiring replacement andparticularly the rollers used in bake oven conveyers where they aresubject to very high temperature and where replacement has to beundertaken with the conveyer in operation.

A further and very important object'is to devise a construction ofroller which will obviate the necessity of replacement of a con-- 1 5veyer section on account of the breaking or seizing of the rollers.

- In the drawings, Figure 1 1s a perspective vlew of my improved roller.

Figure 2 is a perspective view of one of the roller sections separatedfrom the other.

Figure 8 is a perspectlve view of the removed section in a reversedposition from that shown in Figure 2. v

. It has been the custom in the manufacture of traveling conveyers ofthechain type to mount the rollers onthe section in such a manner that whenrollers became broken or seized it was necessary to remove the entiresection. Such a condition necessitates a very considerable loss of timein the use of the apparatus and particularly so in bake oven structureswhere the conveyer is heated to a temperature which prohibits handlinguntil the oven isshut down and the belt allowed I to cool.

The present invention has been devised to overcome these diflicultiesand it consists of two part cylindrical members 1 and 2. Each of themembers is formed with a portion of Y the length semi-cylindrical andthe fiat diametral surfaces 3 of the section 1 are adapted to coincidewith the flat diametral surfaces 4 of the section 2.

The remaining length of the section 1 is formed with the bevelledsurfaces 5 extending in an acute angular direction from the point 6 ofthe bore 7 which are slightly offset from the flat surfaces 3 to theouter per- I {so imeter, thus forming the substantially trians'crews 13the two rollersections may be lift- "ed radially away from the shaftonwhich lock washers.

the rest of the conveyer.

gular faces 8 at right angles to both the faces3. I w

The section 2 of the roller extending be yond the flat diametralsurfaces 4'is formed with the right angularly arranged faces 9 adaptedto abut the faces 8 of the section 1 when they are placed together'andthe in wardly bevelled faces 10 of this extension c portion are adaptedto coincide with the be V-, elled faces 5 of the member '1, the inneredges of thejbevelled faces 10 being offset slightly from the point 6'where the faces 4 intersect the-bore 7 of the pulley section;

It will be seen that the two sections of the pulleys thus described willfit snugly together to, form a complete cylinder'with the faces 8 and 9abutting and the bevelled faces 5 engaging the bevelled faces'IQdefinitely align the two sections and hold them in alignment inoperation without stress upon any holding means for securing the twoparts together.' 1 M The segments of the member 1 between the faces 3and 5 are formed with the parallel threaded holes 11 and holes 12arebored in the segments of the member 2 betweenthe faces 4 and 10 toreceivethe fillis'ter head screws 13. These screws when placed inposition'and drawn tight draw the faces 8 and 9 snugly into contact. IOil holes 14 are bored angularly through bore 7.

I It will be seenthat by simply is oving the they are mounted and inreplacing, the one section may be-dropped on to theother and Iwillalignitself and itis merelyinecessay to secure the members together bymeans of the screws which will be provided with suitable Such a rollerisparticularly adaptable for bake ovens as access to a broken roller maybe hadthrough the side doors of the oven and 5 it will be .merelynecessary to'remove the screws whichcan easily be accomplished with along-handled screw driver and the two parts may then be lifted outwithoutfouli'ng no i Q to

A new roller may be placed'in position through the side doors of theoven if necessary, but the conveyor may be moved along to the end of theoven without the roller 5 where the new one may be placed in positionmore conveniently. g U

The peculiar shape of the roller by the offset of the bevelled sectionsmaintains a solid support for the member carried thereby at all 10times. Further, such construction allows the roller to expand andcontract freely Withoutseizing upon the shaft on Which it is carried, asthe expansion is taken up in the sections separately. 7 The constructionof the roller is extremely simple but very efficient and it iseconomical to manufacture... v V V V lVhat I claim as my invention isr 1.
